Homework Statement What is the average pushing force a human can exert? Homework Equations The Attempt at a Solution I did some research online but didn't come up with anything.

Thank you sooooooo much. You have beeen an amazing help. I am not going to lie, this was the first time i used this website and i was very doubtful but you have totally changed my opinion. I can't thank you enough!

Thank you so much. Youve been a great help! Yes i did mean that a is the length of the diagonal between the lower corner and the cm. I also did mean (a+b). I am sorry but even with your help I am still not quite certain how this formula was ascertained. Could you please try to explain it.

I found this online but it was a website i wouldn't trust. Does it make sense to you. The attachment is a diagram which explains the variables. m=mass, g=gravity F=(m g cos(theta) b) / (a = b)

How would i find the angle that would require the minimum force?

Okay, another question. Would it require less force to tip the block if the force is only horizontal? If so, then we can make it just a horizontal force with no vertical component.

Okay. So i clicked on the torque hyperlink and it was really helpful. I get stuck however when i have to factor in the weight of the block and the center of mass. Do you know how to do that or where i could look to figure it out?

Thanks for the advice. Unfortunately, I don't know anything about torque but i guess i'll have to learn :smile:!

Thankyou for responding. I don't have a specific example. Ill add the following to the given information, sorry it was incomplete at first. Mass- 500kg The prism is oriented with its width of 0.5m in the direction of the (horizontally applied) load. The force is applied in the middle of the...

Homework Statement How much force is required to tip an object? Given- It is a rectangular prism 1m tall, .5 m wide, 2m long. The center of gravity is .75m from the ground vertically and otherwise centered. The force can be applied wherever it is easiest to solve the problem. Homework...
